Technical Abstract

The present disclosure relates to systems and methods for transmitting Standard Dynamic Range (SDR) content. The systems and methods may use a modified Electro-Optical Transfer Function (EOTF) curve to convert nonlinear color values of SDR content into optical output values of modified SDR content. The systems and methods may encode the modified SDR content using eight bits while preventing banding. The systems and methods may transmit the encoded data to a client device for presentation on a display.

Patent Claims
11 claims

Legal claims defining the scope of protection, as filed with the USPTO.

2

2. The system of claim 1, wherein the modified EOTF curve is constrained to 100 nits.

3

3. The system of claim 1, wherein the modified EOTF curve prevents banding in the SDR content.

4

4. The system of claim 1, wherein the modified EOTF curve improves an image quality of the SDR content while encoding the modified SDR content at eight bits.

5

5. The system of claim 1, wherein the modified EOTF curve increases a level of granularity in darker portions of the SDR content.

7

7. The system of claim 1, wherein the standard format corresponds to a specified viewing environment of the display.

9

9. The method of claim 8, wherein the modified EOTF curve is constrained to 100 nits.

10

10. The method of claim 8, wherein the modified EOTF curve prevents banding in the SDR content.

11

11. The method of claim 8, wherein the modified EOTF curve improves an image quality of the SDR content while encoding the modified SDR content at eight bits.

12

12. The method of claim 8, wherein the modified EOTF curve increases a level of granularity in darker portions of the SDR content.

14

14. The method of claim 8, wherein the standard format corresponds to a specified viewing environment of the display.

16

16. The computer-readable medium of claim 15, wherein the modified EOTF curve is constrained to 100 nits and prevents banding while improving an image quality of the SDR content while encoding the modified SDR content at eight bits.
